Best ROM for battery life

My phones is currently plugged into the car charger and has been for the past hour I've been using it. It's gone from 69% to 55% during that time and the only real thing using any juice according to the stats is the screen. This is unacceptable. I'm on an older version of gummynex but I have nothing tweaked as of right now. My screen on time is typically about 14 hours a day and as of now I have to be plugged in pretty much all day. If I could somehow get my phone to last 4 hours without a charge that'd be amazing. I don't think it's possible but maybe someone can help me. Please don't just tell me to search, I want to know every single step I can take please. Thanks in advance.

14 hours a day of screen on time? WTF?
So I'm assuming you have an LTE Galaxy Nexus? Most car chargers will barely put out enough juice to charge the LTE device. You have to up to a higher quality charger.
No ROM is going to help you if you're literally keeping your phone's screen on 100% of the time. It doesn't matter at that point.

you can definitely get 4 hours with stock battery.
AOKP + Franco. Look around forums there are many threads on battery

AOKP Milestone 3 + Franco's kernel are pretty good. But I can have around 3 hours on screen. Maybe it depends on how you use your GNex.

I get around 4-6, I have the extended GSM battery.
pro tip: It's also a good idea to keep your refresh intervals for various apps to a high amount or to a manual refresh

AOKP plus IMO+ Leantweaks
Great combo 5hrs on screen time. Great sleep as well.

I bought a Motorola Car Charger off Amazon for 5bucks and I have verizon Galaxy nexus and it charges my phone even when im using 4g and GPS at the same time. Im also using GummyNex 7.6 rom. So it is possible to get it to charge while on in your car.

14hrs of onscreen time is pretty damn nuts!
You sure that's not a typo?
I probably average about 3-4 hrs a day in an average working business week...
Anyways, to answer your questions, from my personal experience ARDH 2.1.5 as well as Manhattan IC112 give me the best battery life.
ARHD probably just tops it.

u guys have to read it twice, its 14 hours of screen time WITH the car charger plugged in

[KERNEL PATCH] Force AC (fast) Charging

This is for kernel devs only. The patch itself is useless to those who do not/can not compile their own kernel.
I put together this patch for you guys at the request of a few different members here in the nexus S forum who had saw my patch in the gnex forum. This allows one to force AC charging for any charger that is detected as USB (e.g. many car chargers) and pull the full current the charger can support. It also provides additional security when connecting to public charging stations because by forcing AC charging, USB/adb data transfers are disabled, protecting your data.
Fast charge can be toggled by issuing:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
and off:
echo 0 > /sys/kernel/fast_charge/force_fast_charge
Some roms (AOKP) have also implemented toggles.
In addition I have created a toggle fast charge widget that may be used to toggle fast charge on and off right from your home screen:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
For the widget (or any fast charge toggle) to work, you MUST be running a kernel that has this patch implemented.
As a good gesture to support a fellow dev, I ask that if you implement the patch into your kernel, please link to my widget as one means to toggle it. You are of course free to provide other ways to toggle it as well if you so desire.
Kernel devs, if you would like to test the widget yourself to confirm its working, and for convenience of testing, please contact me and I will provide you with a copy. You must show that you are a kernel dev though (i.e. link me to your kernel post so I can match your username).
Here you go. Good luck have fun:
http://www.incredikernel.com/wp-con...wnload.php?id=nexus_s_force_fast_charge.patch

Hopefully we will see this implemented into a lot of our kernels around here. It looks pretty sweet. If I knew how to compile kernels I'd be all over it.

Thanks! I'd like to see this also!

Its been brought to my attention that the AOKP toggle interferes in some way with the widget. I'm going to contact them and see what's up. I think they may be setting the permissions of the fast charge toggle in an undesirable manner.

thank you x 1million!!! I requested this from mathkid about two weeks ago & never heard anything back....I hope this gets implemented now

ahh, thanks for the response I'll write him and thank him for his part in researching this for matrix kernel.

any kernels on the nexus s 4g support fast charge? I cant wait to get this working! Great job!

I've always had a problem of GPS draining my phones battery no matter what ROM I'm running, or what car charger I use, been through about 5 of them. If this helps with that I'm super stoked about this, since it's the only thing that I don't like about my Nexus S.

id love to see how fast this makes charging, considering my phone already charges pretty god damned fast.
•neXus•S4G•ĄØKP•Mïlestøne 4•Aïr Kerneł 3.7•

Does anyone know if this can be ported over to the HP Touchpad?

Anyone have much luck with the fast charge toggle on this kernel? I'm helping my friend who just got a nexus s 4g and setup his touchstone from his palm pre. his phone only detects as USB while on the touchstone even though its a full 1 amp charger. Anyway if he plugs in he gets ac charging obviously. So I had him enable fast charge with this kernel and us NStools. It doesn't seem to work and actually glitches out and charges slower to the point that it never increases even with screen off. It indeed says ac in settings. If he then plugs into regular ac outlet it continues charging slow where it won't increase even a single percent for 20 min. Restoring stock kernel goes back to normal.
Anyone had any luck with fast charge? We're kinda baffled here. I know the nexus s is a slow charging phone already at 750 mA. anyone have any ideas? Thanks.

So I realize this is a bit of an older thread, but since it got bumped anyway...
Isn't this about the same thing as SBC? Meaning, won't this trash your battery very quickly? Fast charging is designed to be something that's only done in emergency situations (which is why people say only to use car chargers in emergency situations) otherwise it will kill your battery. This really shouldn't be something to use in a daily driver kernel.

car chargers charge your phone at a slower rate than a wall charger so no its absolutely fine for car chargers your other part i have no clue.

There are two charge modes: USB and AC. The phone determines the mode by reading the resistance value between the two USB data pins. If the value is zero, the phone charges in AC mode, which draws > 500mA current (eg. wall charging). If the resistance is very high, it charges in USB mode and draws <= 500mA of current (eg. charging from a computer USB port).
What this patch does is it forces the phone into AC mode so that it can draw higher current and charge faster. Hope it clears up your confusion.

That makes a bit more sense, I had my A's and D's crossed there. So basically this just helps speed up the charge if you're charging from a pc then. Gotcha.

Ya mine was running so hot today it wouldn't charge on my car charger (in an a/c'd car) had it on there for 3hrs and it didn't charge past 40% restored back to caulks gb (barely had 8% battery left after restore) and in an hr I was at 90% and the phone was at room temperature.

This happens to me from time to time, usually when using large amounts of data in poor signal areas.
GPS and the car charger usually makes for a hotter than normal device as well. This was true on my evo, tp2 and tp also.

Mine has ran hot on every ICS rom. I havent used any akop or cm9 roms. Mine does it every now and again and all I do is reboot leave it alone for a couple minutes and its back to normal. I haven't ssen a rhyme or reason to when mine runs hot other than when its on and off of a charger. I have changed several things and nothing seems to help. My screen also get hot sometimes but it has been like this now ever since I started using ICS roms 6 or 8 months ago.

Car charger Vs. AC charger
Could part of your problem also be that since the car charger is set on a 12VDC input, but most cars while running are at 13-14VDC, could be pushing a high voltage to your battery than the AC charger? Don't know if that helps just some input. Mine runs hotter (99* F) when I'm charging in the car. 80* F when I'm charging with my AC charger. (My car's voltage while its running is 13.5VDC) I'm running stock ROM with Rogue_ET-1.5.0+ kernel, OC/UV @ 1400 MHz step.

Normal charging voltage for a vehicle is around14 volts. When your engine its off you will see 12.6 volts. Typical cell battery is around 3 volts. Your car charger is designed to reduce that voltage to the proper level. They are designed to handle those fluctuations. I use a oem Motorola charger I got for6 bucks on Amazon. I dont have nearly as many issues as I did with the generic charger I had before. You get what you pay for
Been doing electrical work for over a decade and rebuilt alternators for 3. So trust me when I say I know what I am talking about.

Download Tegrak and try to undervolt your CPU.
CPU gets overworked for many reasons, poor signal, lots of data, many processes, etc.
Overheated CPU overheats battery then battery charging turns itself off.
When I was with AT$T (note my sig), they throttled my data. To them they were just slowing me down. For me, it basically made my phone a brick during the throttled periods because it overworked the processor trying to pull a bowling ball through a garden hose. I made them waive my EFTs because I showed then they were physically damaging my phone with their "new" policy. Sorry for the rant...

I belive you. Lol. Im work on generators and hvac sysytems. Good to knpw though about the chargers.

Oh just found this out. My wife has a cheap charger we have had for years. It just started flaking out on her. If the voltage to the phone gets too high the phone will beep and come up with a warning about the voltage being to high and charging will stop. So your charger definitely is not directly causing the hot battery

Working Fastcharge mode in Vicious Jelly Bean V5 with Faux Kernel.

I am playing with Fastcharge in JB with the Faux Kernel. Here are the specifics of my experiment.
App: Galaxy Nexus Fast Charge (from market). I wish there was a toggle or widget but I'll probably have to wait for AOKP JB.
All charges were done with networking OFF, screen OFF. I would have liked to do a longer experiment but I didn't have time and didn't think extending the experiment time would yield a noticeable difference.
The phone did in fact register as an INTF2 device when I turned on fastcharge, where it shows as a Media Device when it's in USB mode. This is the same as when I had it in ICS (AOKP) with Franco Kernel, which definitely worked (very well).
Phone: Galaxy Nexus LTE
Carrier: Verizon
ROM: Vicious Jelly Bean V5
Kernel: Faux Kernel JB 019
Fastcharge OFF, 10 minutes, USB = 5%
Fastcharge ON, 10 minutes, USB = 9%
I wanted to see if it would also change the voltage/amperage draw from the stock charger that came with the phone.
Fastcharge OFF, 10 minutes, AC = 9%
Fastcharge ON, 10 minutes, AC = 9%
AC was same as expected. I didn't know the kernel had fast charge mode since it doesn't brag this feature but apparently it does.
This is good news considering the poor battery life I've gotten with Vicious JB/Faux Kernel compared to the great life with AOKP ICS/Franco Kernel.

Can a Mod move it please? I never post as you can see. I am not sure where it would belong, as it's more of a Kernel review than anything.

Nexus noob here. What is fastcharge? Does it basically remove any USB connection options and increase the charging speed?

Those guys did compile a GSM version I found it fishing around inside Goo and someplace else. I never flashed it but I did find one (Team Vicious)

1 A = 1 Amp
1 mA = 1 Milliamp (.001 Amps)
A charging AC port can give up to 1.5A through a USB cable, but when connected to a regular port (computer, some chargers), it only provides up to 500mA (0.5A).
What fastcharge does is allow the phone to view the USB connection not as a USB hub or computer, but as a devoted AC charger. This adds much Amperage and vastly improves charging. This allows you to plug into a computer and charge at nearly the same speed as your devoted AC charger. It also helps with car chargers, which for some reason can be stingy.
Some Kernels support this, and many roms have the toggle built in. I started loving it using AOKP, thinking it was BS, but it actually works very well. With AOKP and Franco kernel, I could charge my battery fully from car or USB in an hour, double the time it would take without fastcharge.
Only draw back is you lose the ability to transfer files via that USB connection (the connection to computer shows up as "INTF2" instead of "Media Device." No matter how you feel about it, it's great to have the option to suck some extra battery life, especially considering how crucial my phone is to my existence (I wish I was joking). So now when I'm at my friend's, if he has any device which takes a USB A to USB micro b (what droids use) then I don't need a wall charger and it will have nearly the same effect.
I was testing to see if the custom JB Kernels supported this feature, since I know with ICS and GB, the stock kernels wouldn't allow it. This is very exciting as now AOKP can built in the toggle and don't have to stress about how well it works or whether the majority of kernels support it.

What a spot on post! And, yes, I really like how much AOKP supports, even though I'm not currently using it - who isn't using JB?
Yes, the JB kernels have started to re-implement features as JB is better understood. Franco's is also running great with JB (Official or AOSP).
Please Note: You may forget that you've unleashed the charging potential of whichever connection you're using. Remember, you will need to disable fast charge to use your phone's data connection properly. I'm guilty of forgetting myself from time to time. Nothing like being aggravated at something you did to yourself and can't figure out. lol

Are you talking 3G/4G? I did not know it interferes! Does it interfere even when you're not charging? Have you tried Faux Kernel? I really like Franco but many were saying it conflicted with Vicious. Which Franco are you using? New nightly? I saw that he added JB support but the consensus on the Vicious forum is Faux. It seems alright but not as good as I was getting, battery-wise.
This is such an exciting time to be an Android user with the best (at least most supported) phone!

Any way of getting fast charge setting to stick after a reboot? Seems you have to enable it all the time.

That would depend on what you think is ''much longer''? Fast Charge only works when plugged on something else than the wall outlet. It basically disables the UMS to do so.

Yup, other dude is right you shouldnt need it for a wall outlet. Only off a computer. Try trickster mod. Works perfect for me.

I'll try the trickster mod and see how that goes ... Thanks for the tip. Bwolf 6hrs plus for charging on a stock and even this 4000mAh battery is long I can see 3-4 hr maybe 5hr it just abnormally longer even when plugged to the outlet but thanks guys for the help and further knowledge

The type and length of USB cable used will have a significant impact on how long it takes to charge your phone.
